Benefits of technology

The invention simplifies the process of calculating through scanning along both the latitude and longitude directions. It reduces the number of measuring instruments and simplifies the structure. The nonlinear scanning method saves time and allows for efficient scanning and real-time performance. The use of a rotating polyhedron, scanning galvanometer, and microelectromechanical mirror reduces the mass of the rotating body and increases stability. The amount of rotating body is further reduced using a 2D controllable microelectromechanical mirror. The periodic flash of the flash light helps the system determine the scan cycle and prevents data confusion. The exit light processing module can increase or decrease the exit angle of the exit laser and expand the range of scanning.

Problems solved by technology

This kind of spatial orientation system tends to consist of large measuring equipments, and have long measurement time and poor capability of real-time measurements, thus substantially limiting the application.

Embodiment Construction

[0032]The present application provides an interactive spatial orientation method and system with simple equipments and shorter measuring time, aiming at the drawback of the current spatial orientation with miscellaneous equipment and long measuring time.

[0033]To make the technical feature, objective and effect of the present application be understood more clearly, now the specific implementation of the present application is described in detail with reference to the accompanying drawings and embodiments.

[0034]FIG. 1 is a schematic diagram of the interactive spatial orientation method and system according to the present application. In the axes, the horizontal axis represents the time t, and the vertical axis represents the light intensity 1×. When the measurement is started, a flash signal is given, and the receiving apparatus receives an optical signal with a light intensity that is far greater than or far less than the light intensity of the measured laser. The flash signal is mai...

Abstract

Disclosed is an interactive spatial orientation method and system. The method includes: sequentially scanning, by a scanning apparatus, a receiving apparatus in a first direction and a second direction perpendicular to each other; converting, by the receiving apparatus, received optical signals generated from the first scanning and the second scanning into radio waves carrying results of the first scanning and the second scanning, and transferring the radio waves to a processing apparatus; synthesizing, by the processing apparatus, the results of the first scanning and the second scanning to obtain six degrees of freedom information of the receiving apparatus. The system includes a scanning apparatus; a receiving apparatus; and a processing apparatus.

Description

CROSS REFERENCE TO RELATED APPLICATIONS[0001]The present application claims the benefit of Chinese Patent Application No. 201610281117.0 filed on Apr. 29, 2016. All the above are hereby incorporated by reference.TECHNICAL FIELD[0002]The present application relates to the field of spatial orientation, and more particularly relates to an interactive spatial orientation method and system.BACKGROUND OF THE APPLICATION[0003]Spatial orientation generally uses an optical or ultrasonic mode for positioning and measuring, and derives the spatial position of an object to be measured by building models. A general optical spatial orientation system determines the spatial position of an object by using a laser for scanning and a light sensor for receiving. This kind of spatial orientation system tends to consist of large measuring equipments, and have long measurement time and poor capability of real-time measurements, thus substantially limiting the application.SUMMARY OF THE APPLICATION[0004]T...
